Description

Technical Field

[0001] The utility model relates to the technical field of idler assemblies, and particularly to an idler assembly of a belt conveyor. Background Technique

[0002] A belt conveyor, also known as a belt conveyor, is a mechanical device that conveys materials continuously by frictional drive. It uses a belt as the traction and support device, and conveys materials from the feeding end to the discharging end through the movement of the conveyor belt. Conventional belt conveyors include structures such as a frame and idlers for supporting the conveyor belt and materials.

[0003] During the use of idlers, it is easy to adhere to impurities such as dust and dirt. These impurities will affect the normal operation of the idlers. A large amount of impurities adhering to the surface of the idlers will increase the running resistance of the conveyor belt and reduce the conveying efficiency. The conventional cleaning method is to clean each idler one by one, which is inefficient and troublesome. For this reason, an idler assembly of a belt conveyor is proposed.
